Curled Foam Core

[JayVal]

Do any of you experienced community members know how to combat this?

Pre-curl prevantative measures? Post-curl de-curling techniques?

I had to take a call and I came back to find my board was no longer flat. There was nothing printed or applied to this. And yes, before I get called out on this, the board really was flat before I stepped away.

I will also accept replies on how much of a pain foam core is to work with, because I'm not very fond of the material...

Thanks!

Yeah same thing happened to me

Is it super damp or humid?

Humidity.... flip the board over and let it sit.

I refuse to work with foamcore, too many better alternatives.

We've moved to Dispa board instead of 5mm foamcore.
Stays way flatter and prints better.

Pretty dry in the shop today. Now that I think about it, could it be heat? There's a heater 20-30ft at the top of the shop bay I work in....

Haven't heard of that yet. I will see if we have that available from our suppliers.

I'll try this again... I lost patience when I tried this. lol

Could be heat drying it out but here in AZ we typically see it due to added humidity

We did the display for one of the sponsors of a marathon here (posters on easels & hanging boards) . Set up the night before in huge tent with AC, a 100 yards or so from the beach..We did all our stuff on smooth pvc. Most everyone else used foam board. Event guys shut down the AC for the night & the next morning there was moisture dripping off the canvas from the humidity. All the foam boards had curled into C shapes on the ink side. We looked like we really knew what we were doing even though the reason we used pvc was our hate for working with foam board.

This is an inspiring story that validates my ever growing dislike towards foam board! Thank you for sharing!

This happens to our spoil boards all the time. Seems to lay flat when it's cool in the shop, Once the shop starts to heat a little the moisture leaves the surface much faster then the bottom that is covered. We have found no way to prevent it. When it starts to get bad we flip the table. I would imagine you are experiencing something similar due to the heat of the lamp.

In my experience, aint much you can do for that stuff. anything with a paper face will expand and contract depending on heat and humidity. Even small relative changes can influence the board. Doing 2 sided prints on the stuff is nerve-racking to say the least.

Ok...so when it's laying on the table, which way does it curl? Belly side up? Or belly side down?

"DISPA® delivers everything you would expect from a sign and display board – flat, smooth surface, excellent printability, rigidity and stability – and a unique design made of 100% paper and so DISPA® is fully recyclable."

100% paper and it doesn't warp????

 

[visual800]

we dont use formboard anymore because of this. for your humor a very long time ago I sprayed a 4x8 foamboard with black ons shot and layed it OUTSIDE on a table in the sun to dry. I cannot express this thing almost rolled itself into a damn tube lol. I like foam board but I just dont mess with it

That's right. Even printing on a flatbed with hot lamps.
